SANITARY CUSPIDOR.

Specification of Letters Patent.

Patented Aug. 4;, 1914.

Application filed November 14, 1913. Serial No. 801,019.

To all whom it may concern ie it known that I, MARTIN Pnoorinn, citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Sanitary Cuspidors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in sanitary cuspidors; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a combined side elevation and vertical middle section of the cuspidor; Fig. 2 is a vertical crosssection on the line 22 of Fig. 1; Fig. 3 is a top plan with parts broken away, only one-half of the hood or cover being illustrated; and Fig. 1 is an inside elevational view of the end portions of the locking or brake-band.

The present is an improvement on the cuspidor construction forming the subject matter of U. S. Letters Patent 1,073,167, dated September 16, 1913, issued jointly to myself and Elijah A. Scott; and while contemplating the several objects and possessing the various advantages of the patented construction, the improvement herein has for its main object the simplification of the structure as a whole and the elimination of parts "found undesirable and unnecessary in prac tice.

A further object is to construct a cuspidor from the container of which the operating portions are readily removable so that every portion may be thoroughly scoured from time to time and a sanitary cuspidor in the strict sense, assured.

The advantages of the present invention will be apparent from a detailed description thereof which is as follows Referring to the drawings, 1 represents a vessel or water container provided with a detachable tight-fitting conical hood or cover 2 having a central discharge opening 0, and an outer annular inwardly-turned deflecting flange 3 to prevent any material running over the outer edge of the hood. Located within the container adjacent to the wall thereof, (and removable from the container as presently to be explained) "is a pumpcylinder 5 from the lower portion 01. which leads a flush-pipe 6 which is extended upward along the axis of the container, and is projected through and above the dis charge opening 0 of the hood. The pipe (3 terminates in a peripherally perforated spray-tube 7 provided with a dellecting head 8 above the perforations t oi the tube, the latter being attached to the pipe 6 preferably by screwing and may be removed at any time to gain access to the interior oithe pipe should occasion therefor arise. The piston 9 of the pump is provided with a central opening 0 controlled by a hinge-valve V, the latter being provided with a lip or lug 10 rearward oi? its hingeaxis, said lug being adapted to ei'igage the under surface oi the piston with an opening movement of the valve and thus prevent the valve from dropping too far with the upward stroke of the piston. It is apparent of course, that if the valve dropped too near the vertical, it would not close with the downstrokc of the piston. As in the patent above referred to, the pump cylinder is here provided with a com pression spring S which automatically returns the piston to its raised position when said piston is released by the operator. Leading upwardly from the piston 9 is a stem or piston'rod 11. terminating in a linger-hold 11, and extending a suitable distance above the upper edge of the container.

In the present embodiment of my invention, the stem 11 is guided respectively by the side flanges a, a, of an arm 12, and by said arm and a roller 13 mounted between the ears or lugs a, c, on a spindle 1 1 supported by said lugs, although the roller is not by any means indispensable. The upward movement of the stem 11 (and hence of the piston) is arrested by a pin 15 on the stem striking the roller 13 (or the spindle 1 1: where the roller is dispensed with). The guide arm 12 lies close to the container wall, and is secured at its lower end to a brake-band 1(3 encircling the outer peripheral portions of the pump cylinder, the inner portions of the cylinder walls being snugly emb need by a strap 17 whose ends are sccured to the band 16. In this way the pump is securely tied to the brake-band and may be removed from the container or replaced therein jointly with the brake-band when the latter is deposited in the container or removed therefrom,

The band 16 is a flat spring member (preferably steel or brass) and when expanded against the inner surfaces of the container walls, serves to lock or clamp the pump to the container. One end of the brake-band (or locking band, a name perhaps more appropriate therefor) has pivoted thereto a lever 18 (oscillating in the plane of disposition of the band), said lever having secured thereto at an intermediate point one end of a link 19, the opposite end of the link being pivotally coupled to the opposite end of the band. The distance between the point of connection of the link 19 with the lever 18, and the point of connection of the lever with the band 16 determines the short arm of the lever, the part of the lever beyond thepoint of connection of the link therewith, being the long arm of the lever. The link 19 and the short lever arm thus act as toggle members, and when expanded a throw of the lever toward hinge connection between the link and band) they cause an expansion of the band, whereupon the band is driven into firm frictional contact with the container walls, and the pump with its appurtenances becomes locked to the container. By throwing the lever in the opposite direction so as to break the toggles, the band will be contracted, and hence loosened from the con tainer walls, and the band, together with the pump may be withdrawn from the container and the interior of the latter as well as the parts removed may be thoroughly scoured. Of course, to remove the parts referred to, it is obvious that the cover or hood must be first removed. Necessarily, a recess 1" must be formed in the hoodto allow for the free i piston-pump, a locklng band coupled to the passage therethrough of the stem 11.

Pivoted to suitable brackets m, m, on the bottom of the hood, and on each side of the center of the opening 0 thereof, are the hinge-rods 20 of a pair of gates 21, 21, which normally close across said opening and against the bounding lip or flange h thereof, the said rods terminating opposite the piston stem 11 in inwardly deflected parallel arms 20, 20, adapted to ride over and rest on the pin 15 (or its equivalent), the pin performing herein the double function of arresting the stem and actuating the gates 21. The arms 20 are formed the same as those illustrated in the patent aforesaid, and operate in like manner. The cuspidor herein is likewise provided with a removable strainer plate 22 the same as the plate 13 in the patent aforesaid, is positioned relatively to the pump as in said prior patent, and requires no detailed description in the present connection. It has been found in practice that the strainer 22 keeps the water in the pump compartment C (the compartment into which the water filters through the strainer) sufficiently clean to dispense with the necessity of thestrainer piston such as shown in the patent aforesaid, and consequently in the present embodiment of my invention I employ a piston with a single opening 0.

The operation is substantially the same as in the patented cuspidor, that is to say, as-

, suming that the locking band and the pump have been deposited in the container anu locked to the walls thereof, and the hood deposited in position, with the arms 20, 20, of the hinge rods 20 resting on the pin 15, the stem 11 is depressed, whereupon the water is expelled from the pump-cylinder through the perforations t of the tube 7 carried by the pipe 6. The spray from the perforations washes down the material from the hood through the openingo into the container, the gates 21 dropping to open position with such depression of the stem 11 or downward stroke of the piston. A release of the stem drives the piston upward thus closing the gates, and with a subsequent depression of the stem the same operation or flushing is repeated. The pump operates only on clean water which finds its way into the pump compartment C from the dirty-water compartment C on the opposite side of the strainer 22.

Having described my invention, what I claim is 1. In a cuspidor, a suitable container, a pistonpump, a locking band coupled to the pump-cylinder and insertible into the con-v tamer, and means on said band for expand mg and driving the same into firm frictional engagement with the container walls for 'lockmg SZIlCl' cylmder within the container.

2. In a cuspidor, a suitable container, a

pump-cylinder, and insertible into the container, means on said band for expandingand driving the same into firm frictional engagement with the container walls, a stem leading from the pump-piston to a point above the upper edge of the container, and

a member leading from the band for guidmg sald stem.

3. In a cuspidor, the combination of a suitable container, a piston-pump, a band encircling the outer peripheral walls of the pump-cylinder, and insertible into the con- 'tainer conjointly with the pump, a strap passed over the inner peripheral walls of the pump cylinder and coupled to the band,

a lever pivoted to one end of the band, a link coupled to the opposite end and to an intermediate point of the lever, the latter oscillating in the general plane of disposition of the band, a stem leading from the piston to a point above the container when the pump is inserted into the container, and a guide arm for said stem coupled to the band at point opposite the strap aforesaid.

4. In combination with a container, a pump-cylinder, a brake-band carried by the cylinder and insertible into the container conjointly with the pump-cylinder, toggle members on the band for expanding and contracting the same at will, whereby the band may be locked to, or freed from, the container walls, a spring-contro1led piston in the cylinder, a piston-rod or stem leading therefrom to a point above the container, an arm fixed to the band and disposed on the inside of the container close to the wall thereof, side flanges on the arm for guiding the stem, a pin on the stem, and means on the arm aforesaid for arresting the pin and thereby arresting the movement of the stem and piston in one direction.

5. In combination With a liquid container,

a cover therefor discharging into the container, a pump, a band carried by the pump and insertible conjointly therewith into the container, means for expanding the band and forcing the same into firm engagement with the container walls, means for actuating the pump from a point outside the cover, and a spray device leading from the pump and discharging water on the cover.

In testimony whereof I affix my signature in presence of two witnesses.
